Explosion welding is a solid state joining process in which
explosive energy is used to propel the component metal parts
together to form a metallurgical bond. At the point of impact of
the two components, a thin layer is stripped from both colliding
surfaces and is ejected as a molten metal jet. This jet contains
the surface contaminants and oxides that would otherwise prevent
bonding. The two surfaces are in intimate contact under extreme
pressure enabling the bond to be formed.
